More Details

Intellectual property name: a desulfurizer cyclone mixing device

Corresponding product or project: Tangshan Donghai iron and steel sintering plant project

Core technology: the flue gas from the heating furnace enters the sodium based (NaHCO3) dry desulfurization (sodium based dry) dust removal integrated system. The flue gas is led out from the outlet of the original induced draft fan, and the flue gas heat exchanger is set. The heated high-temperature flue gas is used to heat the soot. The hot flue gas after heat exchange is mixed with the air flue gas to improve the flue gas temperature and meet the reaction temperature requirements of desulfurization and denitration. After passing through the SDS desulfurization and dust removal device, it is led back to the original flue gas for discharge. Two sets of soot desulfurization and dust removal devices and two sets of air smoke desulfurization and dust removal devices are built respectively in 1580 steel rolling line; The flue gas first enters the sodium based dry desulfurization reactor, and the sodium bicarbonate ultra-fine powder is injected into the sodium based dry desulfurization reactor. The sodium bicarbonate ultra-fine powder decomposes into highly active sodium carbonate and carbon dioxide under the action of high-temperature flue gas. The highly active Na2CO3 is fully contacted with SO2 and other acidic media in the flue gas to produce chemical reaction and be absorbed and purified. After desulfurization, the powdery particle products enter the bag filter with the air flow to collect the desulfurization by-products.

Technical indicators achieved: the emission concentration of waste gas particulate matter is less than 10mg / Nm3 (dry basis), which is guaranteed by the original dust removal system. The emission concentration of sulfur dioxide is less than 35mg / Nm3 (dry basis), and the concentration of nitrogen oxides does not increase.
